DETAILED DESCRIPTION

[0022] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0023] The buffer guardrail post of the embodiment of the utility model is described below with reference to the accompanying drawings.

[0024] like Figure 1-Figure 5 As shown, the buffer guardrail post of the embodiment of the utility model may include: two main trough bodies 1, a first connecting member 2, a secondary trough body 3 and a second connecting member 4.

[0025] The two main tank bodies 1 are connected via a first connecting member 2 .

[0026] It should be noted that the two main trough bodies 1 have the same specifications, and the pile planting depth can be determined according to actual usage. For example, when the soil is relatively soft, relevant technicians can connect multiple main trough bodies 1 together through multiple first connecting members 2 to increase the pile planting depth and increase the stability of the column.

[0027] One end of the auxiliary tank body 3 is rotatably connected to a main tank body 1, and the auxiliary tank body 3 is located inside the main tank body 1;

[0028] A plurality of elastic telescopic rods 31 are provided inside the auxiliary tank body 3, and bases 32 are pivotally connected at both ends of the elastic telescopic rods 31, one base 32 is connected to the main tank body 1, and the other base 32 is connected to the auxiliary tank body 3;

[0029] The second connecting member 4 is movably mounted on the auxiliary tank body 3 .

[0030] It should be noted that the high-speed guardrail can be connected to the column via the second connecting member 4 .

[0031] Specifically, during the installation of the column, relevant technicians (eg workers) can calculate the pile planting depth based on the determination of the softness of the soil in the target area, and connect multiple main troughs 1 to adapt to changing road conditions.

[0032] Workers use the first connecting piece 2 to connect the two main trough bodies 1, and then use external piling equipment to insert the two main trough bodies 1 into the soil, and then install the auxiliary trough body 3 and the elastic telescopic rod 31 at the preset position. After multiple columns are piled, workers connect the columns to the guardrail through the second connecting piece 4.

[0033] When the guardrail is hit by external force, the guardrail transmits the force to the main column, the auxiliary trough body 3 pushes the elastic telescopic rod 31, and the auxiliary trough body 3 rotates inside the main trough body 1, combining the deformation of the guardrail plate, the main trough body 1 and the auxiliary trough body 3 itself to buffer the external force.

[0034] In one embodiment of the present invention, Figure 1 and Figure 4 As shown, the first connecting member 2 includes a connecting groove 21 and a plurality of first fixing members 22 .

[0035] A plurality of connection holes 11 are formed on the main tank body 1 , the connection grooves 21 are fitted with the inner walls of the two main tank bodies 1 , and a plurality of first fixing members 22 penetrate the plurality of connection holes 11 and the connection grooves 21 .

[0036] It should be noted that the first fixing member 22 described in this embodiment may be a bolt.

[0037] In one embodiment of the present invention, Figure 1 and Figure 3 As shown, a plurality of connection holes 11 are symmetrically arranged at both ends of the main tank body 1 .

[0038] It can be understood that the connection holes 11 are symmetrically arranged at both ends of the main tank body 1 , which, on the one hand, facilitates mass production of the main tank body 1 , and on the other hand, facilitates connection between two main tank bodies 1 .

[0039] In one embodiment of the present invention, Figure 1 and Figure 2 As shown, the second connecting member 4 includes a connecting plate 42 and a plurality of second fixing members 43 .

[0040] Two first through slots 41 are symmetrically formed on the auxiliary tank body 3 , and a plurality of second fixing members 43 are mounted on the connecting plate 42 . The plurality of second fixing members 43 respectively penetrate the corresponding first through slots 41 .

[0041] It should be noted that the second fixing member 43 described in this embodiment is slidably connected to the first through slot 41 .

[0042] Specifically, when the external guardrail is subjected to an external force, the connecting plate 42 drives the second fixing member 43 to move, and the second fixing member 43 moves inside the first through slot 41, thereby ensuring that the connecting plate 42 can push the auxiliary slot body 3 to rotate.

[0043] In one embodiment of the present invention, Figure 2 and Figure 3 As shown, two arc-shaped through grooves 52 are symmetrically provided on the main groove body 1 , and a limiting rod 51 is provided on the auxiliary groove body 3 , and both ends of the limiting rod 51 are slidably connected with the corresponding arc-shaped through grooves 52 .

[0044] It is understandable that the length of the arc-shaped through slot 52 can limit the position of the limit rod 51 , so that under the action of the elastic telescopic rod 31 , the main slot body 1 , the auxiliary slot body 3 and the elastic telescopic rod 31 are connected into a whole.

[0045] In one embodiment of the present invention, Figure 2 and Figure 5 As shown, a shaft body 61 passes through the auxiliary tank body 3 and the main tank body 1 , a stopper 62 is provided at one end of the shaft body 61 , and a locking member 63 is provided at one end of the shaft body 61 .

[0046] Specifically, during the installation process, the shaft body 61 can be inserted into the rotation point between the auxiliary tank body 3 and the main tank body 1 , and the blocking cover 62 and the locking member 63 can prevent the shaft body 61 from being separated from the main tank body 1 and the auxiliary tank body 3 .

[0047] In summary, the buffer guardrail post of the utility model improves the buffering capacity by arranging an elastic telescopic rod between the auxiliary trough body and the main trough body, which is superimposed with its own deformation. In addition, multiple main trough bodies can be connected together to increase the planting depth of the post to adapt to changing road conditions.
